@Firefox,
Body choice is (AFAIK) not an issue at sanctioned F1 races aside from a Tamiya TCS event. If it is a Tamiya TCS event, you would have to run a Tamiya body, I believe. Otherwise, it should not be an issue. I have run front and rear wings that don't match one another, nor the body (ie an F2012 Ferrari doesn't have to run the F2012 front or rear wings to be ok).
